Abstract
Description
Technical Field
[0001] This utility model relates to the field of portable gas stove technology, and in particular to a gas cylinder detachment mechanism for portable gas stoves. Background Technology
[0002] Portable gas stoves, as portable gas cooking devices, are widely used in outdoor camping, family gatherings, and small catering establishments. Their core function relies on a stable connection to the gas cylinder and easy disassembly. Currently, gas cylinder installation on portable gas stoves on the market typically uses a snap-fit structure for fixation, but the following technical problems commonly exist during disassembly: Firstly, traditional unloading methods mostly rely on users manually inserting or removing the gas cylinder, or using simple lever structures to assist in the operation. However, manual insertion or removal is prone to deformation of the gas cylinder interface or damage to the internal locking parts of the furnace body due to uneven force, and the operation is time-consuming and laborious. On the other hand, existing mechanical auxiliary structures are mostly defective in that they are complex in design and occupy a lot of space, making it difficult to adapt to the compact shell layout of different models of cassette furnaces.
[0003] Secondly, some detachment mechanisms use rigid metal parts that directly contact the gas cylinder clamping part. After long-term and frequent operation, the parts are prone to deformation due to metal fatigue or friction and wear, which can lead to problems such as detachment jamming and failure, seriously affecting user experience and equipment lifespan.
[0004] Third, the existing detachment structure has poor adaptability. Different brands or models of portable gas stoves require customized detachment mechanisms due to differences in the size and position of the gas cylinder clamping part, which increases production and maintenance costs and limits the versatility of the product.
[0005] Therefore, it is necessary to develop a gas cylinder removal mechanism for portable gas stoves that is compact, easy to operate, durable, and compatible with mainstream gas cylinder specifications, in order to solve the problems of inconvenient removal, easy damage, and poor adaptability in the existing technology. Utility Model Content
[0006] The main technical problem solved by this utility model is to provide a gas cylinder detachment mechanism for a portable gas stove, thereby solving one or more of the aforementioned prior art problems.
[0007] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a gas cylinder removal mechanism for a portable gas stove, which is installed inside the housing of the portable gas stove and located on the side of the gas valve. The innovation lies in that: the gas cylinder removal mechanism includes an assembly, a removal component, and a limiting plate; the assembly includes an installation plate connected to the housing, a vertical plate perpendicular to the installation plate, and a positioning plate perpendicular to the vertical plate, which together form a Z-shaped structure; the removal component is rotatably connected to the vertical plate by assembly bolts, and has a pressing plate at the top and an inwardly bent lever plate at the bottom; the limiting plate is set on the vertical plate to prevent the lever plate from flipping outward.
[0008] In some embodiments, the mounting plate is provided with at least two fixing holes, which are circular or oblong holes, for bolting or snap-fitting to the housing.
[0009] In some embodiments, the upright plate is provided with a first mounting hole, and the detachable part is provided with a corresponding second mounting hole. The mounting bolt passes through the first mounting hole and the second mounting hole and cooperates with the washer to form a rotatable connection structure.
[0010] In some implementations, the pressing plate is a flat or curved plate. When the pressing plate is pressed, its bottom surface is in complete contact with the top surface of the positioning plate, forming a stable force support.
[0011] In some embodiments, the bending radius of the lever is 30°-60° and it is made of a flexible metal material, used to abut against the gas cylinder latch to achieve the detachment operation.
[0012] In some embodiments, the limiting plate is a protruding structure extending from the edge of the upright plate toward the unloading part, or a baffle fixed to the side of the upright plate by bolts, used to limit the rotating plate from going beyond a preset plane.
[0013] In some embodiments, the gasket is an elastic gasket or an anti-slip gasket, fitted between the mounting bolt and the detachment component to reduce rotational friction and prevent the bolt from loosening.
[0014] The beneficial effects of this utility model are: through structural optimization and linkage design, this utility model effectively solves the problems of inconvenient operation and poor durability of existing gas cylinder detachment for portable gas stoves, and has significant practicality and promotional value.

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort, wherein: Figure 1 This is a schematic diagram of the gas cylinder detachment mechanism for a portable gas stove according to this utility model.
[0016] Figure 2 This is a front view of a gas cylinder detachment mechanism for a portable gas stove according to this utility model. Detailed Implementation
[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] This utility model embodiment includes: a gas cylinder detachment mechanism for portable gas stoves, applicable to various types of portable gas stoves. Its core function is to achieve rapid separation of the gas cylinder and the gas valve through a mechanical linkage structure. The specific implementation method is described in detail below with reference to the accompanying drawings.
[0019] like Figure 1 and Figure 2 As shown, the assembly consists of a mounting plate 101, a vertical plate 102, and a positioning plate 103, which are integrally stamped or welded, forming a Z-shaped structure. The mounting plate 101 is a rectangular metal plate (2-3mm thick, preferably made of Q235 steel) with two waist-shaped fixing holes 501 (8mm long axis, 5mm short axis), which are fixed to the gasket shell by M4 bolts. The waist-shaped hole design can compensate for the machining error of the shell mounting surface, facilitate fine-tuning of the assembly position, and improve installation efficiency. The vertical plate 102 extends upward perpendicular to the mounting plate 101 (20-25mm high), and a positioning plate 103 (with the same thickness as the mounting plate 101) is provided on its top. The positioning plate 103 is parallel to the mounting plate 101 and extends horizontally (15-20mm long). When the assembly is fixed inside the shell, the positioning plate 103 is located directly above the gas valve, providing a support base for the pressing action of the detachment part 201.
[0020] The detachment component 201 is an L-shaped metal part (preferably made of 65Mn spring steel, 3-4mm thick). Its top is a pressing plate 202 (the width matches the positioning plate 103, and the surface can be provided with anti-slip texture), and its bottom is a lever plate 203 that bends inward (bending arc 45°, with a rounded end and a radius of 2mm). The detachment component 201 is connected to the upright plate 102 by mounting bolts 301. The upright plate 102 has a mounting hole (5mm in diameter) in the middle, and the detachment component 201 has a corresponding mounting hole (5.2mm in diameter). After the mounting bolts 301 (M5×15) pass through the two holes, an elastic washer 302 (1mm thick, made of phosphor bronze) is installed between the bolt head and the detachment component 201. The elastic washer 302 has two functions: first, to provide pre-tightening force to prevent the bolt from loosening; and second, to reduce the frictional resistance when the detachment component 201 rotates, ensuring that the pressing operation is easy and smooth.
[0021] When the user presses the pressing plate 202, the release part 201 rotates downward around the mounting bolt 301. At this time, the bottom plane of the pressing plate 202 is completely in contact with the top plane of the positioning plate 103 (contact area ≥80%). The positioning plate 103 serves as a support point to prevent the release part 201 from shifting when pressed. At the same time, the lever 203 presses down and bends inward, with its end abutting against the protrusion of the gas cylinder locking part. Through the lever principle, the vertical force of the press is converted into a horizontal thrust, thereby pushing the locking part to unlock and realizing the rapid release of the gas cylinder.
[0022] The limiting plate 401 is a raised structure (5mm high, 3mm wide) extending from the edge of the upright plate 102 toward the release component 201. The distance between the limiting plate 401 and the side of the lever 203 is controlled at 0.5-1mm. When the release component 201 rotates, the limiting plate 401 restricts the lever 203 from shifting outward (away from the gas valve), ensuring that the lever 203 is always in the optimal release plane (the vertical plane aligned with the gas cylinder latching part), thus preventing the lever 203 from deforming or shifting due to long-term use and extending the service life of the mechanism.
[0023] The working principle of this technical solution is as follows: When it is necessary to disassemble the gas cylinder, the user presses down on the pressing plate 202 of the disassembly component 201. The disassembly component 201 rotates around the mounting bolt 301, causing the lever 203 to move inward and abut against the gas cylinder locking part. The positioning plate 103 provides stable support for the pressing plate 202 to prevent the disassembly component 201 from tilting. The limiting plate 401 restricts the lever 203 from flipping outward to ensure that it accurately acts on the locking part. Finally, the locking part is unlocked by the lever force, and the gas cylinder is disassembled. After releasing the pressing plate 202, the disassembly component 201 automatically resets under the rebound force of the elastic pad 302, waiting for the next operation.
[0024] The advantages of this technical solution are: Compact structure: The combination design of the "Z"-shaped assembly and the L-shaped detachable part 201 takes up little space and is compatible with the shell layout of different models of portable gas stoves; Easy to operate: The press-type linkage structure requires only one hand to operate, and the detachment process takes ≤1 second, significantly improving the user experience; High durability: The spring steel release part 201, the friction compensation design of the elastic pad 302, and the anti-displacement function of the limit plate 401 ensure that the mechanism maintains stable release performance after more than 6,000 cycles of operation. High adaptability: The waist-shaped fixing hole 501 of the mounting plate 101 and the 45° bending arc design of the lever plate 203 are compatible with the clamping structure of the gas cylinder of mainstream brands on the market.
[0025] In summary, this utility model effectively solves the problems of inconvenient operation and poor durability of existing gas cylinder detachment for portable gas stoves through structural optimization and linkage design, and has significant practical value and promotion potential.
